RATION OF LLIN 01S.

LUBRICATIYNG-BEARNG.

To all whom t may concern.' y

Be it known that I, CARL OSCAR ANDER- soN, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of lllinois,have invented .certain new and useful Improvements in Lubricating-Bearings, of which the following is a specification.

of the spindle by which the separator bowl is supported and operated.

The object of the invention is to provide a novel form of bearing for the spindle which may be inexpensively produced, and which will embody simple and reliable means for feedin an abundant supply Yof oil to the spindle to insure free running thereof. These spindles operate at high speed. Their general tendency, induced yby such high speed, is to throw off the-oil, so that difficulty is experienced in supplying a sufficient quantity of the oil toV aiford adequate lubrication. liereindescribed bearing these objections are obviated and the spindle is 4always provided with the requisite quantity of lubricant.

The invention also seeks to provide a lubricating bearing wherein provision is made for positive feeding of the lubricant through- `outthe entire length of the bearingthereby eliminating heating of the bearingby reason of failure of the oil to reachlall parts thereof. i

With these general objects in view, and others which'will appear as the lnature of the improvements is better understood, the invention consists substantially in the novel construction, combination and a'rrangeinenty ing of the invention;

frame proper of the machine having asso ciated therewith the usual bearing body-ier casing 11 in which is disposed the usual separating bowl (not shown).A `Also associated with the frame 10 is -t-heworm wheel 12 actuated from the crank shaft 13,"said wheel being inclo'sed in Said frame andworlring'within an oil cavity le at the interior of said frame? rlihe'niuneral 15 designates the usual worm spindle which supports and operates at its upperend the separating bowl, beforeA referred to; 16 designates the stop screw for the spindle 15; 17 is the upper bearing for the spindle 15, and 18 designates Athe springs for holdingthe bearing 17 in placein the openingformed atthe lower endof the casing 11.l The parts enumerated are'of common construction,

preferably those, found in the Sattley separa-V tor-of corni'nerce,` with theexception of the the subject 'of .andv includes the presentr'invention. Y,

tion of the spindle 15 within the bearing 17, the vtendency being'for the oil to be thrown ofi' during the lhigh speed rotation of the spindle. To prevent this the presentinvention contemplates'such a construction of the bearing 17 as to provide an abund-ant supply of oilfor the :bore thereof and the spindle working within the bore, and to maintain a proper How-of: the oil tothe bearing while construction of the bearing-'17,. This Vforms v the spindle is in operation. To this end it is proposed to equip the-bearing with an oil reservoir at'itslower end which vwill be continuously supplied 'with oil from "the vcavityli'during'the operation of the lworm wheel 12,v andlalso to provide means in connection with the .oil reservoir, whereby to establish a-positive feed of the' oil from the reservoir to the bore of the bearing and the spindle operating within said bore. Several formsl of construction by which .the yobject ofthe invention fniayfbe attained are dis-v yoil through said opening 29.

closed, but thatv illustrated in Fi 2 is regarded as the preferred form.

eferring, therefore, to Fig. 2 it will be observed that the bearing includes an elongated sleeve 19 'having a cylindrical bore 2O extending the purpose of which will presently appear.

At the lower end of the sleeve 19 is formed a horizontal receiving flange 23, and at the lower extremity of said sleeve 19 is an annular rib 24 which surrounds the lower end of the bore 2() and provides at such end a cavity 25, the diameter of' which is greater than the diameter of the bore 20.' The cavity 25 provides an oil pocket or reservoir which is fed by a plurality of inclined openings orpassages 26 extending from the juncture point of the flange 23 with the sleeve 19 into said cavity 25, said passages 26 being also disposed in radial'relation to the bore .20, as clearl illustrated in Fig. 4. When, therefore,`o1l is deposited on the receiving flange 28 it enters the passages 26, and by reason of the inclination of said passages the oil will gravitate into the cavity or pocket 25. The exterior of the rib 24 is grooved to provide a bead 27, and mounted `on said rib 24 is arclosure cap 28 having a central perforation or opening 29 fo-rthe reception of the worm spindle 15 when the bearing is assembled thereon. The diameter ofA the opening 29 is the same as the diameter of the bore 2() 0f the sleeve 19; hence, when the bearing is associated with the worm spindle 15 thelatter fills the bore 20 and the opening 29 so that the pocket or `cavity 25 is closed against the exit of the l By reason of the bead 2? formed on the rib 2,4 the edges of the closure cap 28,1nay be crimped into the annular groove by which said bead is forl'ned, thereby effectually holding the' closure cap on the rib 24.

lt has been stated that one of the Vobjectsrcf the invention is to provide means for positively feeding the oil into the bore y20 andthrough the latter so that the. portion of the spindle 15`worlring therein will be properly lubricated. Thisis effected by an inclined deiiector 30 which extends transversely from the rib 24 to a point coextensirewith the vedge of the bore "20, and likewise' extends longitudinally from the end of the sleeve 19 t the lower'edge o-f the rib 24.

' The deflector 30 constitutesfa diaphragm or partition within the pocket 25, and when the bearing is assembled on the worm spindle 15 the inner edge of the deflector 30 is adjacent to; said spindle.V The rotary flow of theoil,therefore, inthe pocket 25, in-

ducedv by the; rotation Vof the'ispindle 15, is interrupted by; thedeflector V30, and the oil is. thusturned inwardly against the. spindle,l

the deflector 30 servin to create a pressure by reason of the forcing of' the oil thereagainst under the rotation of said spindle.

.Consequently with the o-il thus obstructed in its rotary flow it is directed against the spindle and this pressure causes the oil to rise along the spindle within the bore 2O and to flow upwardly through the sleeve 19 to the upper end thereof. To assist in this flow the bore 20 may be provided with a.

spiral groove 31, but this is not essential7 and may be dispensed with if desired. AS the oil is discharged at the upper end of the sleeve 19 it is received by the cup-shaped flange 21 and when a sufficient quantity has been gathered by said flange it will liow downwardly thro-ugh the discharge opening 22 and be received bythe cavity 14.

To preclude any oil that may accumulate in the cup-shaped flange 21 being thrown outwardly therefrom by the rotation of the spindlel 15 a perforated cover *31a may be placed over said flange, said cover surrounding the spindle 15, as illustrated in Fig 1. This will confine the'oil to the flange 21 and its only point of exit will be through `the discharge opening 22. With the parts assembled as illustrated, in Fig. 1, Sullicient quantity of oilis placed within the cavity 14 of the frame v10 so that its upper level will be at approximately the point indicated by the dotted line in Fig. 1. The surface of the oil is therefore slightly above the lower edge of the worm wheel 12, .As the wheel 12 is rotated the oil is gathered thereby, carried to the upper portion of the cavity 14 and splashed by `the wheel onto the bearing 19. As the -oil is caught by the receiving fiange 23 it passesinto the openings 26, and the latter convey the oil to the poclret 25. that these passages 26 are radially disposed and are inclined with respect to the pocket oill continues throughout the rotation of the Vspindle 15, and as it lis 'forced outwardly through the upper endof the bore By reason of the fact` it accumulates on the cup-shaped flange 21 yand is again returned to the cavity 134 where it is repeatedly splashed by the operation of the worm'wheel 12 onto the bearing 19 in the manner described. It will thus be seen that an abundant supply of oil is constantly provided for the bearing, and the positive feed of the oil through the bearing is effected by the means hereinbefore described.

clined deflect-or 35. In this instance the deflector 35 is formed integral with the cap 32' and extends up to the lower edge of the sleeve 19. v

The arrangement illustrated in Fig. 5 shows the -adaptation of the invention to lbearings not particularly constructed for lubricating purposes. Y

Fig. 6' illustrates a furtherl form of` the invention wherein the same is included as an integral part of the construction ofthe sleeve 19. In this form-the lower end of the sleeve 19 is provided with a head 36 provided at its interior with an annular groove 37 formed by an enlargeinentof the bore 20, said groove 37 providing the cavity for theroil. Within the groove37 is an inclined defiector 38 Aperforming the same functions as the deflectors`39 and 35 ofthe forms shown in Figs. 2 and 5. The head 3G islilrewise formed with an openingv39 for receiving the spindle 15. f

Obviously,the act-ion of the oil in being fed to and as it iiows through the constructions illustrated in Figs. 5v and 6 is the saine as in the other forms ofthe invention.
